I bet after a certain time period if you have not submitted the requested document to the best of your ability that GP will block you from bidding. Fill it out say you no longer have the vehicle and move on.

I think it's been in the works for a week or so. I got an email from GP last week telling me I needed to fill out an euc on a humvee I bought in 2015. I replied to them that I already did an euc on this item and they said it was a glitch that sent out the email. Probably them setting up to send...

Rear seal can't hurt but it takes a special tool and you don't want to find out you did it wrong when the truck is all put back together.

Seems like all the m939 trucks have been taken down on GP. Save for one private sale and one m923.

Maybe it's only a2s

I looked on my GP account it has an euc form open to fill out for a pile of m939 trucks I won over the last 3 years. Most of them are long gone. And they are all bunched into one euc. So I couldn't put different info for different trucks depending on what happened to them.

Is there a part number for the complete adapter?

Great

No but have had to replace plenty of the speed sensors. Im ok with the stock road speed I would rather have the low end pulling power over a few more mph. I dont go far in my trucks.

On the back under the transmission is an output speed sensor. Around 65 bucks online. Easy to replace held on with one screw. If its real bad you will get a fault code. But if its just a little off then you will start getting odd shifting.

Ok unblock the front gladhands and you will have parking brakes. It's a dangerous situation you have unintentionally created. The air leak on the front emergency side is usually caused by the check valve behind the bumper.

I stopped buying used ones they are all take outs like yours with worn keys. If all else is good on yours sometimes you can get a rebuild kit for the keys. There are a few different part numbers that are all wtec3 keypads. As long as they look the same and the connector is the same they all seem...

The pads look like they are against the hub in the pic

Did you put a multimeter on the fuel solenoid contacts with the dash switch on? Outer terminal is positive. Go from the outer terminal to chassis to see if it's a bad ground. Fuel solenoid comes on with 24v power relay. Could be on a breaker though. To access codes the trans control needs to be...

You cannot block off either front gladhand. You must fix the cause of the air leak there. By blocking off the front red gladhand you are inadvertently feeding air into a towing release circuit for your spring brakes.

Looks correct to me. Truck is held by spring brakes. When you put the dash valve in park does the truck roll? But you can still step on the brake pedal and stop? Do you have an air leak at your front red gladhand and you blocked it off so you can build air?

I have the laptop, software and comm box. Do you know where one can get a Y cable? Is the Y cable the same for M939A2 and LMTV use?

Not always on lmtv. Just indicates a hardware fault. The air tank pressure switch not closing will cause a time out error and give 5 solid leds. I believe pneumatic valve not responding can do the same.

Whats the best way to interface with the lmtv ctis control? Its my understanding that on the A1 C7 trucks that have data bus you can use a laptop with the dana software and access it thru the engine diagnostic port. Not sure about 3126 A1 trucks though. Supposedly there is an elusive Y cable in...

I thought they used them to power aircraft electrical on the ground when the engines were off. Most of the civ ground power units are all large like 70k and up.
